To all whom it may, comm:

Be it known that I, Eman N. Hnsoocx, a citizen of the United States, anda resident of the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Continuous Trolley Systems, of which theifollowin is-a specification, taken in connection wit the accompanying drawings, which form a part of the same. 1'.

This invention relates to a continuous trolley system and one which can be installed at the minimum expense. It further relates to certain details of construction which will be described in the specification and pointed out in the claim.

Previous to my invention it hasbeen old to have continuous trolley systems in which i a plurality of drive trolleys have been used with one or more trailing trolleys connected with each driving trolley, the driving trolleys bein driven electrically, the power being suppfied by a supplemental rail extending entirely around the trolley system. The" equipment for such a trolley system is quite expensive, requiring the original outlay for the power trolleys, and the supplemental rail to sup ly current to these power trolleys. Besides it has been found in practice that they are comparatively expensive to operate and make considerable noise, which in many locations where such trolleys are used, is very objectionable.

B 'my invention I form my continuous trol ey system entirely out of what, in the other system, would be trailing trolleys and provide driving means to enga with some of the trolleys, or their connecting members. Preferably I arrange a short flexible driving member adjacent to the trolleys to engage with one or more of them, but to eng c with less than the total number of trol eys or their connecting members. This permits me to arrange the trolley system for any desired layout and, to have my flexible driving member engage with a few onl of the trolleys or connecting members which will operate all the trolleys economically and with comparatively no objectionable noise. My 3 stem can be installed at one-half to onet ird of the initial cost of the other old system and can be run more economically.

In the accompanying drawings I have shown illustrative embodiments of my invention in which the same reference nu- Specification or Letters Patent.

F g. 7 1s a side elevation of another modi-. fication showing a diflFerent form of driving member and connecting members.

In the illustrative embodiments shown in the drawings, 1 is a continuous trolley stem comprising acontinuous track 2, which may be laid out as the exi encies of the job demand, a plurality of troTleys 3, 3connected together by connecting members, which in the form shown in Fig. 1, are plates 4, 4, and a driving member 5 which as shown in Fig. 11s a short link belt 6 cooperating with the engaging surfaces carried by the moving trolle s. i

Th s track 2 is sup orted by the hangers 7 wh1ch are held to t e wall or other sup port 8 by any suitable means such as'bolts 9. The trolleys 3. are provided at either end with U-shaped members 10, 10 in which are mounted thewheels 11, 11 on the axles 12, 12; one of the wheels 11 riding on the top of the track 2 and the other wheel 11 riding on the underside of the track.

These trolleys are connected together by any suitable means. Preferably I connect them together by means of the connecting members 4, 4 which are shown in Figs. 1,2 and 3. .Through the upper and lower U- shaped members 10, 10, I mount pivoting studs 13, 13 which connect the plates 4, 4 to the different trolleys and at the same time permit the plates to rock or move relativel to each other and to the trolleys. In this form of my invention I have extended the studs 13 letting their shanks14 form'a pin ofa or engagi surface to en in the links of the link It 6. On the shank 14 I mount a nut 15 which serves to preventaccidental disengagement of a trolley and its connecti members.

e link belt 6 is mounted over pulleys 16, 16 carried by the shafts 17 17, one or both of which may be a power Instead of forming thestud 13 with a projecting shank to be engaged by the flexible dri member 5 I may, in some instances,

rovide the trolleys with connecting mem- 018 18, 18, Fig. 4* one end of which 19 may be turned up to cm a projectl surface to cooperate with the driving mem r whatever form that member may be.

Of course many other forms of my invention may be made. I have shown one or two for p of example. In the modification in ig. 5, the connecting member, connecting the trolleys 3, 3 is a link belt 20. With this form I may use a sprocket wheel 21 as a driving member.

Another modification of my invention I have shown in Fig. 7, in which the trolleys 3, 3 are connected together by flexible means, such as a rope or similar member 22, which is wrapped, for exam le, around the pins 23, 23. In this form ma use a flexible driving member 24 provid with teeth 25 projecting tively short flexible to engage with 'the trolleys. The flexible driving member passes around a driving sheave 26, the cooperating sheave being omitted from Fig. 7.

Of course any suitable formof carrier is o erated b m stem. For ose of i ustration I hive shown one f ri af of carrier 27, Fig. 3, though it is to be understood that any form of carrier may be used.

' Having thus described this invention in connection .with several illustrative embodiments thereof to the details of which I do not desire to be limited, what is claimed as new and what it is desired to secure by Letters Patent is set forth in the appended claim:
